My new installation of LMDE seems to work very well, but update manager is giving me the following error message.Please let me know if this is something which I need to address or if it will sort itself.

Thanks

Not sure! Sorry, ppa's means nothing to me. I have just installed LMDE on my new hard drive and it seems to work fine. Please clue me in if I need to set it up differently. I may not know what to do, but I'm pretty good at following instructions!

I had thought using update manager was the simplest way of keeping LMDE up to date now, but again that's my inexperience talking.

no problem- you installed lmde and it's working fine (that's good to know)- now you find out that there's one application that you need/you are used to have in previous installs and here you go sudo add-apt-repository whatever- problem: yes. that command is ubuntu specific (and derivatives like mint main edition) and won't work in debian- problem: yes. even if it worked you would easily break your install because mixing both (ubuntu and debian) is not recommended and most of the times won't play nice.- ppa's http://www.makeuseof.com/tag/ubuntu-ppa ... explained/- now the real question: what app you wanted to install? (what are you missing in debian?) what ppa was that?

No new package as such, I had just noticed the shield on update manager had gone blue which I assume is telling me there are updates/upgrades of some sort available. So I refresh to find out what's going on. Result I seem to remember there was one update to mint themes or something similar, but for the life of me I can't remember exactly now, so I clicked on install updates and the result was the error message. Apologies if that's no great help.

The only residual problem I have is with the BBC_iplayer_desktop installation. I have installed adobeair which is required to install the iplayer_desktop but the installation will not proceed because the system will not grant rights to the software to gain access to the storage space which happens to be in /opt/BBC_iplayer etc I have got round this by simply using get_iplayer which is not quite as neat a solution but works and also provides me with mp4 files which will play on my android whereas the BBC iplayer files do not.

I think I'm fiddling at the edges here so don't waste too much time sorting me out, much appreciated though it is!

Thanks have updated. Have not actually checked yet but the update ran correctly with no error messages. I'm still at a loss as to how the ppa was added. I have not knowingly added it. Could it have been part of a normal update which somehow got missed or which didn't install correctly at the time?
